Huasun offers 0BB heterojunction solar modules with modern zero busbar technology

Abu Dhabi, United Arab Emirates (ots/PRNewswire)

Huasun Energy, the world's largest manufacturer of heterojunction (HJT) products, has introduced its latest innovation in high-efficiency modules with ground-breaking Zero Busbar (0BB) technology. This cutting-edge development has been seamlessly integrated into Huasun's mass production lines, including the large format rectangular Himalaya G12 and Everest G12R series units. Through innovative improvements in printing processes, front layer soldering, micro-solar tapes, ultra-thin silicon wafers, and packaging and sealing technologies, Huasun has significantly increased the electrical, optical and temperature coefficient performance of HJT modules, thus increasing the competitiveness of its product range.

As 0BB technology moves toward industrialization, there are differences in specific implementation methods between companies. Huasun's approach primarily involves welding and spreading, providing advantages such as stronger adhesion, better hot spot resistance and carrier film removal.

When producing 0BB cells, Huasun adopts the simpler two-stage screen printing (SP) technology to achieve superior product quality and improve electrical and cell-to-module (CTM) performance compared with superconducting multiconductor (SMBB) products, which has significant advantages in terms of open circuit voltage (OCV). ), conversion efficiency and unit performance.

“Huasun's 0BB modules use a front layer soldering process, which provides the following advantages, among others: reliable welding, low contact resistance, improved hot spot resistance, lower hot spot temperature and higher module reliability,” added Christian Combs, BD Director. In Europe, Huasun: “In addition, the design reduces the metal cover on the back, increases the light receiving area and achieves bifaciality by up to 90%.”

0BB technology supports the trend toward thinner silicon chips by providing higher reliability with no main network, thinner tapes, less compression, and lower hash rates. By adopting light diversion (DS) packaging and PIB edge sealing technology, Huasun's HJT 0BB modules provide a significant increase in power generation capacity. This advancement leads to more reliable products for utility owners and commercial, industrial and residential rooftop PV projects.

The successful mass production of HJT products “G12+0BB” and “G12+R+0BB” represents another milestone for Huasun in its pursuit of increased efficiency. Huasun is committed to manufacturing and promoting HJT technology and continues the widespread adoption of 0BB high-efficiency modules, which provides state-of-the-art heterojunction products with higher conversion efficiency, improved reliability and lower cost of electricity (LCOE) for PV projects worldwide.
